Summary
Many uses of electrospun scaffolds — from tissue engineering to filtration and composite reinforcement — depend not just on producing nanofibres but on controlling their orientation, because aligned fibres guide cell growth and give anisotropic mechanical behaviour. This study sets out to identify which electrospinning variables most strongly govern fibre alignment when fibres are collected on a rotating drum. The authors examine how the collector's rotational speed, together with the other governing process parameters, affects the degree of alignment and the resulting fibre morphology, and distil the findings into practical guidance on the settings that matter most for producing well-aligned polymer nanofibres. By pinpointing the dominant parameters, the work helps researchers reproducibly fabricate oriented nanofibre mats for applications that require directional structure.
